A righteous one can sing and be glad.

A righteous one can sing and be glad (Prov. 29:6).

Even the wicked hate a man of integrity (v. 10), who expose their unfruitful deeds of darkness (Eph. 5:11)

And commit sin of placing a snare to the righteous (Prov. 29:6),

The righteous sing and is glad even in that tribulation (v. 6).

The reason is because the righteous believe that

God will lead the wicked to fall into his own trap (28:10) and will deliver the righteous from trouble (12:13).
